Non-Majorana-origin of the half-integer conductance quantization elucidated by multi-terminal superconductor-quantum anomalous Hall insulator heterostructure
Anjana Uday, Gertjan Lippertz, Bibek Bhujel +2
Chiral one-dimensional transport can be realized in thin films of a surface-insulating ferromagnetic topological insulator called quantum anomalous Hall insulator (QAHI). When supe…
Characterizing the chemical potential disorder in the topological insulator (BiSb)Te thin films
Jens Brede, Mahasweta Bagchi, Adrian Greichgauer +6
We use scanning tunneling microscopy and spectroscopy under ultra-high vacuum and down to 1.7 K to study the local variations of the chemical potential on the surface of the topolo…
Propagation, dissipation and breakdown in quantum anomalous Hall edge states probed by microwave edge plasmons
Torsten Röper, Hugo Thomas, Daniel Rosenbach +7
The quantum anomalous Hall (QAH) effect, with its single chiral, topologically protected edge state, offers a platform for flying Majorana states as well as non-reciprocal microwav…
Selective-Area Epitaxy of Bulk-Insulating (BiSb)Te Films and Nanowires by Molecular Beam Epitaxy
Gertjan Lippertz, Oliver Breunig, Rafael Fister +5
The selective-area epitaxy (SAE) is a useful technique to grow epitaxial films with a desired shape on a pre-patterned substrate. Although SAE of patterned topological-insulator (T…
